Due to the fact that relate with Body Detector, as we know human body itself possesses a fairly large of capacitance to the ground (earth),so such a body approaches the positive capacitor, it value will rise.If then,one could fine a means to detect such an increase in capacitance,one would have an effective means of detecting the presence of human body.
Based from this paragraph, it explain that human body itself have a capacitance. Due to the description above, it show the related info same goes to Body Detector. Since Body Detector using metal sensor, it possible application can be as a safety switch,a touch sensor,a tamper alarm and secure shield to people. It show that the Body Detector can detect the presence of human up to 80cm away if attached to lighter metal objects.
Refresh back about the presentation that we has done this morning, i just remind back the words that my lecturer say when we told him about the fact that relate with our Body Detector. He simply asked either the fact is true or not. I can say its a true fact,but he say it seems fake. He explained to us about the basic structure of how the capacitor is made and produce. However it is, the fact is still the fact. Maybe there are some part that fake to believe but somehow it still a fact.
"Sometimes there are some fact behind the fake..you just need to discover it! "
